3 MW of power were going to be added to the company’s existing facilities in Rugeley and Daventry as well as its newest location at Doncaster. Now comes word that Amazon’s fulfillment center in Tilbury will add 4.074 MW of rooftop PV to the small solar system already there. The new installation will be composed of 15,000 solar panels (270 watt each) manufactured by Jinko Solar. But unlike the new systems at Rugeley, Daventry, and Doncaster, the installation at Tilbury will include a 3.77 MW Tesla battery made up of 28 Tesla Powerpack storage units. The system is being planned and installed by Push Energy.

The Tilbury building consumes about 20 GWh of electricity every year. Rated at 3.5 GWh, the new rooftop system will meet just under 18% of that annual total. All of the electricity from the solar panels will be consumed onsite. According to filings with local authorities reviewed by Solar Power Portal, the Tesla Powerpack batteries will be charged from the local grid and will primarily be used to decrease grid connection stress during periods of peak demand.

The Tilbury system will use 82 Huawei inverters as part of the installation. Asked if the company plans to add battery storage to any of its other locations in the UK, an Amazon spokesperson declined to comment.
